Description
===========
Using the current version of python-cinderclient on master with Nova, an attempt to attach a volume will fail. It appears that the new parameter "api_version" in the cinderclient is the cause.
Steps to reproduce
==================
1. Deploy Devstack
2. clone the python-cinderclient repo to get the latest version on master
/opt/stack$ git clone git://git.openstack.org/openstack/python-cinderclient.git
3. remove the existing cinderclient from /usr/local/lib/python2.7/dist-packages
sudo rm -rf /usr/local/lib/python2.7/dist-packages/cinderclient
4. link the latest version:
sudo cp -rs /opt/stack/python-cinderclient/cinderclient /urr/local/lib/python2.7/dist-packages/
5. Create a volume
cinder create 1
6. Boot a Nova instance
nova boot --image <image_id> --flavor 1 VM0
7. Attempt to attach the volume
nova volume-attach <instance_id> <volume_id> /dev/vdc
Expected result
===============
Volume attach succeeds
Actual result
=============

This passed the tempest run with the commit on master, so it must be a local user error. I wouldn't copy files around like this, pip install it to be sure, you could have stale pyc's that are causing issues.
